In computing, a slot may refer to one of several expansion slots on a computer motherboard, including the ISA slot, PCI slot or AGP slot. It can also refer to an internal peripheral device, such as a CD-ROM drive or an SD card reader. In addition, a slot might also refer to the physical reels on a slot machine or a video game console.
As microprocessors became more commonplace, manufacturers of slot machines began to use them to assign different probabilities to each symbol on each reel. This gave the illusion that some symbols were much closer to hitting than others. This was especially effective when a machine was offering a higher payout for putting in more coins, since the player would perceive that they were increasing their odds of winning by doing so.
Modern slot machines usually display a Pay Table area that lists information on jackpot amounts for specific reel combinations. This can be permanently displayed on the machine, or, with more advanced touchscreen displays, an interactive series of images that can be switched between to view all possible combinations.
Problem gamblers often describe experiencing a state of dark flow during slots play. Dixon et al. suggest that this is because players’ normal mentations tend to be characterized by habitual bouts of mind-wandering, while slots provide an exogenous reinforcing distraction in which the player’s attention is captured by the enticing sights and sounds of the machine. The more extensive this auditory feedback is, the more intense the dark flow.
